Juan Mata said the prospect of being substituted in Manchester United's Europa League victory against Rostov on Thursday spurred him on to score the game's only goal.
The quarter-final first legs will be played on Thursday 13 April, while the second legs take place the following week, on Thursday 20 April.
In a stop-start Premier League campaign Manchester United head to the Riverside on Sunday to face Middlesbrough in what is the second of just two league fixtures in a seven-week period between mid-February and the beginning of April.
Mourinho believes they should have a longer break between the fixtures, and reiterated his frustration at United's situation.
"Play on Monday with 10 men, enjoying five hours on the M6 coming back to Manchester. Lyon have experienced and talented players, so it'll be hard". We go Sunday at 12 o'clock. Why?
Mourinho's early diagnosis suggested a lay-off of around three weeks, which would see Pogba miss at least three league games in total.
"Yeah. I don't know for sure, but for sure, no Middlesbrough and no national team".
"Middlesbrough have just sacked the manager as well, so it will probably be even tougher than what it would have been".
While most pundits would have said something less ferocious and ultimately sympathised with Jose because the club do have a lot of fixtures to play in a short space of time, Keane made his point from personal experience. "It is going to be even more hard for us but we go until our limit, like Marcos Rojo".
"The boys are wonderful boys". When I watch marathons and people go to their limit, I don't think it is amusing, and I don't think it's amusing some of my players in six weeks play 11 matches.
I will remember forever when I spoke to the Uefa delegate in Rostov.
"It was an accumulation of fatigue", Mourinho said.
"I've never heard so much garbage in my life", Keane said in his post-match analysis. But it's not to laugh at all.
It is all getting more rosy for Man United in the Europa League and they couldn't have asked for a more decent draw after they were paired with Belgian side Anderlecht in the last eight of the competition.
"In Portugal, every team in Europe plays on the next Monday". Aren't we good enough in the Premier League to have more teams in Europe at this stage?
